Vehicular Mud Guard With Inside Flow Regulating Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular mud guard structures fail to effectively restrain turbulence of air on the vehicle rear side of the wheel assembly, allowing wind to disturb the vehicle body and potentially allowing mud or water splashed by the tire to hit the underfloor.
Innovation Solution
A vehicular mud guard structure featuring a mud guard portion and an inside flow regulating portion, where the mud guard portion is positioned at the rear end of the wheel house with its lower end projecting towards the vehicle lower side, and the inside flow regulating portion is adjacent to the mud guard portion, extending from the upper end towards the vehicle lower and rear sides to redirect wind flow and prevent turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mud guard is positioned to block mud and water effectively, then the mud guard function is improved, but air turbulence on the vehicle rear side increases
Solution Approach 1:
The mud guard structure is divided into two functional segments: the mud guard portion (main body) and the inside flow regulating portion (air flow control element). This segmentation allows each portion to independently perform its specific function - the mud guard portion blocks mud and water while the inside flow regulating portion manages air flow to reduce turbulence on the vehicle rear side.
Solution Approach 2:
The inside flow regulating portion acts as an intermediary element between the mud guard portion and the vehicle rear side air flow. It mediates the air flow path, guiding it smoothly around the wheel assembly to prevent direct turbulence from reaching the vehicle rear side, while the mud guard portion continues to perform its primary function of blocking mud and water.
2Object-affected harmful factors
If the mud guard lower end projects toward the vehicle lower side to block mud, then mud guard effectiveness is improved, but air flow disturbance increases
Solution Approach 1:
The structure is segmented into the mud guard portion that projects downward to block mud, and the inside flow regulating portion that extends toward the vehicle rear side to control air flow. This segmentation allows the downward projection to effectively block mud while the air flow regulation portion simultaneously manages the air flow path to minimize turbulence.
Solution Approach 2:
The inside flow regulating portion extends in the vehicle width direction from the mud guard portion, adding a dimensional element that intercepts and redirects air flow before it can create turbulence on the vehicle rear side. This dimensional extension allows the structure to address both mud blocking and air flow control simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mud guard structure effectively secures the function of a mud guard while restraining turbulence of air on the vehicle rear side of the wheel assembly, preventing mud or water from hitting the underfloor and redirecting wind to minimize disturbance.
Implementation Method 1
when a travel wind (hereinafter, the travel wind is referred to as a 'first travel wind') flowing on the inner side of the wheel assembly in the vehicle width direction in the wheel house hits the inside flow regulating portion, for example, the first travel wind flows toward the vehicle rear side along the inside flow regulating portion. This restrains the first travel wind from flowing toward the vehicle lower side, thereby making it possible to restrain turbulence of the air on the vehicle rear side of the wheel assembly.

AI summary
A mud guard portion is placed on a vehicle rear side relative to a rear tire. This makes it possible to restrain mud or the like splashed by the rear tire from hitting an underfloor. Further, an inside flow regulating portion is provided adjacently to an inner side of the mud guard portion in the vehicle width direction, and the inside flow regulating portion extends from its upper end toward a vehicle lower side and toward the vehicle rear side. Hereby, when a travel wind flowing on an inner side of the rear tire in the vehicle width direction in the wheel house hits the inside flow regulating portion, the travel wind flows toward the vehicle rear side along a deflection wall portion of the inside flow regulating portion. Accordingly, turbulence of the air on a vehicle rear side of the rear tire due to the travel wind is restrained.
